FIGURE 6. Lower-extremity lymphoscintigram from patient with history of lymphadenitis in right groin because of herpes zoster (shingles) affecting her right buttock and inguinal area. Shown are immediate images in anterior and posterior views (left), late images (about 3 h after injection) in anterior and posterior views (middle), and superimposition of anterior emission scan on transmission scan (right). Inguinal node visualization on right and dermal backflow on medial aspect of upper thigh are minimal, suggesting lymphatic obstruction of superficial system. Ant = anterior; Post = posterior.
